Most fun: BARD

EASIEST TO MASTER: DRG

3) HARDEST TO MASTER: SMN

4)HIGHEST DPS: BLM (my main) ENOCHAIN +Raging strikes = +25% damage. Highest burst damage in the game, plus spell speed is easily enhanced to put yourself at the top of the list. Bad part about BLM is hate control and eno upkeep. You mess up eno and it throws off an entire fight. Good thing is that once you get the cast count down, it becomes a lot easier.
